Understanding the Colours Supplied

The wall plate has an underclad and a top cap. These serve different purposes and are not necessarily supplied in the same colour.

• Underclad: the finishing trim visible from beneath the roof. This matches the colour selected when ordering.
• Top cap: the upper cover of the wall plate, which requires suitable flashing over it during installation.

Ordering brown? Your wall plate will have a brown underclad and a grey top cap. A brown top cap is not available. The brown underclad provides the colour finish seen from inside or beneath the structure.

Why Flashing Is Required

The wall plate profile does not sit flush against the host wall to create a continuous weather-tight seal. Although the assembly incorporates seals, these do not replace the flashing required at the wall junction.

Flashing bridges this junction and directs rainwater from the wall onto the roof surface, helping prevent water from tracking behind the wall plate.

A bead of sealant alone is not a suitable substitute for flashing. The junction needs a properly formed flashing detail that covers the top cap and sheds water onto the roof.

Recommended Flashing Detail

We recommend suitable lead flashing, correctly specified and installed for the roof and wall construction.

The flashing should be securely detailed into the host wall and dressed over the wall plate’s top cap to provide effective weather protection. Its coverage must suit the roof pitch and profile, allowing water to drain onto the roof without leaving exposed gaps.

Any alternative flashing system must be suitable for this particular wall-to-roof junction and compatible with the roofing materials. Follow the roofing system and flashing manufacturer’s installation guidance, including requirements for overlap, fixing and movement.

Important Information Before Ordering

• Fixtures and fittings are not included. Select suitable fixings for your host wall construction and the loads of the completed roof.
• Check the system’s limits before purchasing. Self Supported Glazing Bars have specific maximum projections and permitted sheet widths. Make sure your proposed roof dimensions are within the limits for your chosen bars.
• Experienced installation is required. This product is recommended for skilled DIYers or tradespeople who can assess the supporting structure, secure the wall plate correctly and complete the flashing detail.
• Suitable flashing is essential. The wall plate does not create a weather-tight wall junction on its own. Flashing must cover the top cap and bridge the junction between the wall and roof. Sealant alone is not sufficient.

Which Fixings Are Required?

Glazing Bars to the Roof Components

The installation drawing identifies:

These are the bar connection fixings, rather than the masonry fixings used to attach the wall plate to the building. Use the correct compatible bolts, nuts and washers for the system, following the supplier’s installation specification.

Wall Plate to the Building

The wall plate must be secured through its structural aluminium profile into a suitable load-bearing wall. The drawings do not specify the diameter, length or spacing of these wall fixings.

Suitable structural masonry screws or anchors may be appropriate, but the correct fixing depends on the wall material, its condition, the required embedment depth and the loads from the roof. Any render or other surface finish must also be allowed for when selecting the fixing length.

Your installer should select fixings with manufacturer-confirmed suitability and load capacity for the actual substrate and application. A single screw size cannot be recommended for every installation.

Fixtures and fittings are not included. Installation is recommended for skilled DIYers or tradespeople.
